New Revision: 51917
URL: http://svn.reactos.org/svn/reactos?rev=51917&view=rev
Log:
[USBOHCI]
- Remove dead code
- Silence traces
- Pass status & DoneHead as parameters to dpc routine
- Move IUSBRequest cleanup code into new function and use it for bulk / control transfer
cleanup
- Fix bugs in AllocateEndpointDescriptor. It did not take the device address into account.
It also did not respect the direction of the descriptor
- Implement support for bulk transfer requests
- Handle irp completion in CompletionCallback
- Tested in Windows XP SP3 + Vbox 4.04 + USB2.0 disabled + ReactOS usbstor + USB mass
storage device
- OHCI Mass storage support is now also ready
- Next interrupt transfers
